List apps. Optionally filter by project_id.
AI agents call list_deployments to retrieve information from PlugLayer MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries deployment information without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with optional filtering, presenting minimal security risk even if misused by an AI agent.
From the tool's definition Tool name 'list_deployments' and description 'List apps' indicate a retrieval operation with no mutation.
Attacks that exploit this kind of access
List apps. Optionally filter by project_id. It is categorised as a Read tool in the PlugLayer MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PlugLayer MCP Server MCP server in PolicyLayer and add a rule for list_deployments: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches PlugLayer MCP Server. Nothing to install.
list_deployments is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_deployments rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_deployments. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_deployments is provided by the PlugLayer MCP Server MCP server (pluglayer/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
